Check Digit Verification of cas no

The CAS Registry Mumber 505065-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,5,0,6 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 505065-18:
(8*5)+(7*0)+(6*5)+(5*0)+(4*6)+(3*5)+(2*1)+(1*8)=119
119 % 10 = 9
So 505065-18-9 is a valid CAS Registry Number.

An iminodiacetate-modified conjugated polyelectrolyte for fluorescent labeling of histidine-tagged proteins

Cai, Kai,Tan, Ying,Tan, Chunyan,Wu, Jiatao,Wu, Pan,Liang, Jiamei,Liu, Shuwen,Zhang, Bibo,Jiang, Yuyang

, p. 4191 - 4194 (2017)

The iminodiacetate-Ni2+-hexahistidine system is extensively used in protein purification. In this study, an anionic conjugated polyelectrolyte (CPE) with a poly(p-phenylene ethynylene) backbone and iminodiacetate side chains, named PPEIDA, was designed and synthesized. Recognition and visualization of hexahistidine-tagged (His-tagged) proteins using PPEIDA was demonstrated.
